The secured in any suitable manner, such as byweldintermediate guard. members 15 are pivotally m ing or the'like. Thebase 1 is provided with open connected to links '16 and said links 16arepivings through which fastening devices 3 can be otally connected tobottom guard members 17. inserted, in order to connect the base 1 to thefloor Each bottom guard member 1'7 is turnably conof the building.nected by means of a hinge 18 and a hinge-pintle $0 The head of thestandard 2 is provided with a 19 to the bottom of the standard 2. Thebottom m5 U-shaped member 4. Said member 4 is connected edge of eachbottom guard member 1'7 substanto the head of the standard 2 by, anysuitable tially abuts the base 1. fastening devices, or by welding orthe like. As shown in Fig. 1, each of the standards 2 As shown in Fig.6, each U-shaped retaining has apair of bottom guard members 17associated member 4 is provided with outwardly bent lugs 4a. therewith.One of said guard members 17 is prom vided at its bottom with a turnedor hook-shaped edge 17:. The other is provided at its top with a turnedor hook-shaped edge 17b.

Referring to Fig. 2, it can be seen that adjacent guard members 17 ofadjacent units can be caused to interengage by means of said edges 17aand 1712.

As shown in Fig. 1, each bottom member 1'7 may be adjustably secured tothe adjacent member of the hin e 18, in order to allow for anyinequalities in the floor. For this purpose each member 17 is providedwith a vertical slot 20 and a pin 21a slidably retains the members 17 inposition, While permitting a limited vertical movement thereof. One ofthe upper guard members '7 of each unit is provided with an ordinaryclamp 21 by means of which adjacent upper members 7 of adjacent unitsmay be clamped to each other.

As shown in Figs. 1 and 6, additional means may be provided forconnecting each standard firmly to the floor. These additional means maycomprise a bent strut 23, whoseupper end is connected to the standard 2by means of a clamping device 24.

As shown in Fig. 6, the lower end of, said strut 23 is laterally offset,and said lower end may be connected to the floor by means of fasteningdevices 3a.

The guard arms can be upwardly turned while the brackets 5 and 5a areheld parallel to each other, and the parts can then be connected bymeans of a chain 26 which is connected to the top of the standard 2.

Referring to Fig. 6, it can be seen that the guard arms of the units canbe held parallel to each other in order to guard the long side of anopening. Likewise, said guard arms can be held perpendicular to eachother, in order to apply the unit to the corner of an opening.

When the parts of the device are in thepositions shown in Fig. 7, thebrackets 5 are perpendicular to the head of the standard 2, so that thedevice is then very compact. I

I have referred to the members 5 and 5a a bracket members, butit isclear that they could be replaced by any suitable form. of hinge device.As shown in Fig. 1, when the bottom guard members 17 are turnedupwardly, they may abut the stop members 9.

I have shown a preferred embodiment of my invention, but it is clearthat numerous changes and omissions can be made without departing fromits spirit.

I claim: I
